    This did the job:

    SELECT * FROM db1.dataset, db2.dataset where extract(year from db1.dataset.timestamp) = extract(year from db2.dataset.timestamp)
and
extract(day from db1.dataset.timestamp) = extract(day from db2.dataset.timestamp)
and
extract(month from db1.dataset.timestamp) = extract(month from db2.dataset.timestamp)
and
extract(hour from db1.dataset.timestamp) = extract(hour from db2.dataset.timestamp)
and
extract(minute from db1.dataset.timestamp) <= extract(minute from db2.dataset.timestamp)+5
and
extract(minute from db1.dataset.timestamp) >= extract(minute from db2.dataset.timestamp)- 5
